How is trigger finger recognised?

It is usually noticed as a catching or clicking when a finger bends, morning stiffness and occasional tenderness. A clinician confirms the diagnosis with a physical examination.

Which doctor should I see first?

You can start with your primary care (Family Medicine) doctor, who can assess symptoms and refer to Orthopaedics, Hand Surgery or physical medicine specialists as needed.

When is this an emergency?

If the finger becomes suddenly locked with severe pain, numbness, a pale or cold finger, or signs of poor circulation, seek urgent evaluation at a nearby health facility.

Can everyday changes help prevent it?

Yes: limit repetitive forceful hand tasks, use ergonomic grips and take regular breaks. If symptoms persist, seek professional assessment.

Health guide

Trigger finger

Trigger finger causes a catching, snapping or locking sensation when a finger or thumb bends. It can be accompanied by stiffness, tenderness and difficulty straightening or bending the digit. The sections below explain how it develops, common signs, which specialists may assess it, and practical steps for daily life.

What trigger finger is and how it develops

Trigger finger arises when the flexor tendon that bends the finger does not glide smoothly through its sheath. Narrowing of the sheath or a small nodule on the tendon increases friction, so the tendon can catch and cause a snapping or locking feeling. The change usually develops gradually and is linked to repetitive finger movements in many cases.

Typical symptoms and when to seek urgent care

Common signs include a catching or ‘click’ when the finger moves, stiffness (often worse in the morning), local tenderness, and difficulty fully straightening or bending the finger. Seek urgent medical attention if the finger suddenly locks with severe pain, develops numbness, turns pale or cold, or shows signs of impaired circulation.

Who is more likely to get it and common triggers

Trigger finger can occur at any age but is more often reported in middle age and later. Conditions such as diabetes and certain inflammatory disorders are associated with higher risk. Repetitive gripping or hand tasks, forceful hand use, and hormonal changes (for example during pregnancy) can be contributing factors.

How it is assessed and which specialists to consult

Diagnosis is usually clinical, based on symptom history and a hand examination; imaging is not commonly needed initially. Assessment and management options may involve Orthopaedics and Traumatology, Hand Surgery, primary care (Family Medicine), or Physical Medicine and Rehabilitation specialists.

Everyday measures and when to see a professional

Reducing repetitive, forceful hand tasks, using ergonomic tools, taking breaks, and avoiding prolonged gripping can help limit symptoms. If pain, stiffness or movement problems affect daily activities, consult a health professional for assessment and guidance.
